      Sluggish adoption of emerging electronic government (eGov) applications continues to be a problem across developed and developing countries. This research tested the nine alternative theoretical models of technology adoption in the context of an eGov system using data collected from citizens of four selected districts in the state of Bihar in India. Analysis of the models indicates that their performance is not up to the expected level in terms of path coefficients, variance in behavioural intention, or the fit indices of the models. In response to the underperformance of the alternative theoretical models to explain the adoption of an eGov system, this research develops a unified model of electronic government adoption and tests it using the same data. The results indicate that the proposed research model outperforms all alternative models of technology adoption by explaining 77 % of variance in behavioural intention, with acceptable values of fit indices and significant relationships between each pair of hypothesised factors.
    • Emerging markets from a multidisciplinary perspective: challenges, opportunities and research agenda

      This book examines prominent issues in the Emerging Markets (EM) from a variety of disciplines in order to make useful societal contributions through knowledge exchange. EMs offer enormous opportunities, but realizing them is both challenging and risky due to inherent uncertainties of such markets. EM’s also have unique characteristics that makes them different from developed countries. This causes implications for both theory and practice. These markets necessitate substantial adaptations of developed theories and approaches employed in the Western world. This book investigates problems specific to emerging markets, and identifies new theoretical constructs, hypotheses (re)development, and emphasizes institutional contexts. The chapters in this book establish new conceptual and theoretical paradigms from multidisciplinary perspectives concentrated in the areas of information systems, electronic government, and digital and social media matters. The book focuses on topics in these areas such as digital enterprises, sustainability, telemedicine, and Information Communication Technology (ICT) and surveys the potential challenges and opportunities that may arise. These concepts and topics covered in this book are vital for making the global economy more equitable and sustainable.
    • An Empirical Validation of a Unified Model of Electronic Government Adoption (UMEGA)

      In electronic government (hereafter e-government), a large variety of technology adoption models are employed, which make researchers and policymakers puzzled about which one to use. In this research, nine well-known theoretical models of information technology adoption are evaluated and 29 different constructs are identified. A unified model of e-government adoption (UMEGA) is developed and validated using data gathered from 377 respondents from seven selected cities in India. The results indicate that the proposed unified model outperforms all other theoretical models, explaining the highest variance on behavioral intention, acceptable levels of fit indices, and significant relationships for each of the seven hypotheses. The UMEGA is a parsimonious model based on the e-government-specific context, whereas the constructs from the original technology adoption models were found to be inappropriate for the e-government context. By using the UMEGA, relevant e-government constructs were included. For further research, we recommend the development of e-government-specific scales.E-
    • Re-examining the Unified Theory of Acceptance and Use of Technology (UTAUT): Towards a Revised Theoretical Model

      Dwivedi, Y.K.; Rana, Nripendra P.; Jeyaraj, A.; Clement, M.; Williams, M.D. (2019-06)
      Based on a critical review of the Unified Theory of Acceptance and Use of Technology (UTAUT), this study first formalized an alternative theoretical model for explaining the acceptance and use of information system (IS) and information technology (IT) innovations. The revised theoretical model was then empirically examined using a combination of meta-analysis and structural equation modelling (MASEM) techniques. The meta-analysis was based on 1600 observations on 21 relationships coded from 162 prior studies on IS/IT acceptance and use. The SEM analysis showed that attitude: was central to behavioural intentions and usage behaviours, partially mediated the effects of exogenous constructs on behavioural intentions, and had a direct influence on usage behaviours. A number of implications for theory and practice are derived based on the findings.
